氨苄青霉素含量测定方法为咪唑法,降解物的测定方法为碘量法,这两种方法操作程序繁琐,条件要求严格,结果极易出现误差,用电位滴定法代替咪唑法和碘量法可避免因上述因素产生的误差,从而达到定量准确的目的。 Ampicillin content determination method for the imidazole method, determination of degradation products for iodine method, the two methods of operating procedures cumbersome, the conditions are strict, the results prone to error, with potentiometric titration method instead of imidazole and iodine can be Avoid the error caused by the above factors, so as to achieve quantitative and accurate purpose.
